Problems solved by technology
[0004] The hydraulic cylinders used in most fields use external oil circuits to supply and discharge oil to the hydraulic cylinders. The hydraulic cylinders with external oil circuits are simple in principle, easy to implement, and relatively low in production costs, but the oil circuit settings It is easy to damage the oil pipe due to collision outside the cylinder, which will cause the hydraulic cylinder to fail to supply oil. The performance and reliability of this external oil supply hydraulic cylinder are relatively poor

Abstract
The invention discloses a hydrocylinder with a built-in circular oil-way. The hydrocylinder with the built-in circular oil-way comprises a fixed cylinder barrel element and a movable cylinder barrel element movably arranged in an inner cavity of the fixed cylinder barrel element, wherein the fixed cylinder barrel element comprises a fixed cylinder barrel and a piston rod arranged in the center of the inner cavity of the fixed cylinder barrel in a parallel mode, the piston rod and the fixed cylinder barrel are connected and fixed in the bottoms by a flange, the inner wall of the fixed cylinder barrel and the outer wall of the piston rod form an annular hollow cavity with a closed bottom; the movable cylinder barrel element inserts into the annular hollow cavity from the top and can conduct up and down piston motions; a first oil-way and a second oil-way are vertically arranged side by side in the rod body of the piston rod, an upper end of the first oil-way cross breaks and penetrates through the side wall of the piston rod, and the second oil-way vertically penetrates through the top surface of the piston rod. According to the hydrocylinder with the built-in circular oil-way, the first oil-way and the second oil-way are arranged inside the hydrocylinder with the built-in circular oil-way, which makes hydraulic oil cycle inside the hydrocylinder so as to effectively avoid that the hydrocylinder can not supply oil when an oil tube is damaged due to external crash. The hydrocylinder with the built-in circular oil-way has a reliable and stable performance.
Description
technical field [0001] The invention relates to an oil cylinder technology, in particular to a hydraulic oil cylinder with a built-in circulating oil circuit. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and can perform linear reciprocating motion. It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0003] A common hydraulic cylinder mainly includes a cylinder and a piston assembly. The part of the cylinder cavity with the piston rod is the rod cavity, and the part of the cylinder cavity without the piston rod is the rodless cavity. The oil circuit supplies oil and discharges oil in the rod inner cavity and the rodless inner cavity in turn to push the piston rod to reciprocate and...
